Common Mistakes When Saying I’m Not Feeling Well Professionally
1. Giving Too Much Medical Information
You do not usually need to describe symptoms, diagnoses, medication, or other private details simply to explain an absence.
Better approach: State that you are unwell and explain the practical impact on your work.
2. Being Too Vague About Your Availability
Simply saying “I’m not feeling well” may leave colleagues wondering whether you are working, taking leave, or available for urgent matters.
Better approach: Add a clear statement such as “I’ll be taking the day off” or “I’ll have limited availability.”
3. Sounding Too Casual
Phrases such as “I feel awful” or “I’m really sick” may be inappropriate in formal professional communication.
Better approach: Choose neutral expressions such as “I’m feeling unwell” or “I’m dealing with a health issue.”
4. Apologising Excessively
Being unwell is not something that requires a long apology.
Better approach: Briefly acknowledge any inconvenience and focus on the necessary arrangements.
5. Promising a Return Date Too Quickly
You may not know how long recovery will take.
Better approach: Give an update when you have reliable information rather than making an uncertain promise.
6. Ignoring Workplace Procedures
A professional message does not replace your employer’s official sickness or absence process.
Better approach: Follow the required notification procedure and use the appropriate communication channel.
7. Hiding a Serious Impact on Your Work
Being overly vague can create problems if your health significantly affects deadlines or responsibilities.
Better approach: Communicate the work-related impact clearly while keeping personal medical details private.
